This GPS shield works great with any \"Arduino shaped\" board that has SPI and UART pins available and is designed to log data to an SD card. Or you can leave the SD card out and use the GPS for a geocaching project, or maybe a music player that changes tunes depending on where you are in the city.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e-165 dBm sensitivity, 10 Hz updates, 99 channels\u003c\/li\u003e\n\u003cli\u003eLow power module - only 30mA current draw, half of most GPS's\u003c\/li\u003e\n\u003cli\u003eAssembled \u0026amp; tested shield for Arduino Uno\/Duemilanove\/Diecimila\/Leonardo (not for use with Mega\/ADK\/Due)\u003c\/li\u003e\n\u003cli\u003eMicroSD card slot for datalogging onto a removable card\u003c\/li\u003e\n\u003cli\u003eBuilt-in data logging to flash\u003c\/li\u003e\n\u003cli\u003ePPS output on fix\u003c\/li\u003e\n\u003cli\u003eInternal patch antenna + u.FL connector for external active antenna\u003c\/li\u003e\n\u003cli\u003ePower, Pin #13, and Fix status LED\u003c\/li\u003e\n\u003cli\u003eBig prototyping area\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe shield is built around the MTK3333 chipset, a no-nonsense, high-quality GPS+GLONASS module that can track up to 33 satellites on 99 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built-in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only 30 mA during navigation.\u003c\/p\u003e\n\u003cp\u003eThe MTK3333-based module has external antenna functionality. The module has a standard ceramic patch antenna that gives it -165 dB sensitivity, but when you want to have a bigger antenna, you can snap on any 3V active GPS antenna via the uFL connector. The module will automatically detect the active antenna and switch over! Most GPS antennas use SMA connectors so you may want to pick up one of our \u003ca href=\"\/zh\/products\/sma-to-ufl-u-fl-ipx-ipex-rf-adapter-cable\"\u003euFL to SMA adapters\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eEach order comes with one assembled and tested shield, a stick of 0.1\" male header.
